Crop rotation involves planting different types of crops sequentially on the same land. This practice helps in pest and disease management by disrupting the life cycles of pests and pathogens that are specific to a particular crop. It can also improve soil fertility by varying nutrient demands and allowing for the inclusion of cover crops or legumes that fix nitrogen. Diversification of crops grown over time is an inherent part of the practice.
What practice allows farmers to improve soil fertility, diversify their crops, and reduce pesticide costs by naturally breaking the cycle of weeds, insects, and diseases?
